ciliate oak scale

Ciliate oak scale (Eulecanium ciliatum) is a soft scale insect in the family Coccidae, found in Europe. Like other soft scales, the adult female forms a protective waxy or leathery scale cover under which she lays eggs and overwinters. Eulecanium ciliatum is associated with oak (Quercus) as its primary host, though it may also occur on other deciduous trees. The species feeds by piercing plant tissue and extracting phloem sap, and heavy infestations can weaken host branches; however, it is generally not considered a major economic pest. The name ciliatum refers to fringed or ciliate margins of the scale cover or body. Scale insects of the family Coccidae are widespread in temperate and subtropical regions, and many European species are incompletely documented in terms of distribution and population status. Eulecanium ciliatum has not been formally assessed by the IUCN. Natural enemies including parasitoid wasps, predatory beetles, and lacewings help regulate scale insect populations in forest ecosystems. The taxonomy of European Eulecanium has been subject to revision, and several historical records may require reassessment given updated species concepts. Oak forests across Europe support a rich community of specialist scale insects, many of which provide food for insectivorous birds during the nesting season. Conservation of mature oak woodland benefits the entire community of oak-associated invertebrates.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
